The TEPCO Fukushima Daiichi Nuclear Power Station, working in a hurry to get rid of water contaminated with high concentrations of radioactive material has hindered the work.Of these, the Unit 2 trench After stopping the outflow of contaminated water to sea water trapped in the tunnel, called a high concentration, which rose 10 centimeters so far, TEPCO has strengthened monitoring.The TEPCO's Fukushima Daiichi nuclear power plant is not unusual equipment such as an earthquake the night of April 7, and work is proceeding for the recovery of continued cooling. According to TEPCO, over the treatment of contaminated water that interferes with work, in that the first discharging contaminated water to accumulate high levels of basement Unit 2 turbine building first, the condenser begin to move is that the central processing facility or waste steam condenser to remove water as soon as work is over. In addition, during the morning of April 09, the evening of April 8, the water level of high levels of contaminated water trapped in tunnel No. 2 is called trench, a centimeter rise further, since the outflow to the sea stopped, rose water is now 10 centimeters.The height of the ground surface of the water from the trench is 94 centimeters in that there's at 7:00 am on April 9, the situation is not immediately filled, and strengthen the monitoring of water level TEPCO , the leakage path in a hurry or have a leak out from where the contaminated water. The process of releasing contaminated water into the sea from a relatively low level waste disposal facility has been central to the continued April 09, 7700 tons are released so far, leaving about 800 tons has been finished and released in April 09 if all goes well. However, to avoid the danger of hydrogen explosion in advance, by injecting nitrogen gas into the work of the Unit 1 containment, 98% from previous 99.98% purity of the gas to increase, and nitrogen gas through the hydrogen and oxygen reduces to enter, and to reduce the risk of explosion. In Unit 1, at 7 pm April 07 before the earthquake surface temperature of the reactor was 223.3 degrees, after the earthquake temporarily, but rose nearly 40 degrees at 6:00 am on April 09 At the time down to 240.5 degrees. Cause the temperature rose, so far not well understood, TEPCO has decided to continue to closely monitor the injection of nitrogen gas while. Additionally after 10, using a small unmanned helicopter equipped with infrared cameras, shooting conditions and equipment could not be confirmed until this has been to make use of the process for consideration for future work.
